CHURN-DASHER.

SPECIFICATION forming part of Letters Patent No. d18,403, dated December31, 1889.

' Application filed May 8, 1839. $erial No. 310,019. (No model.)

To aZl whom it-may concern:

Be it known that I, DANIEL A. FISKE, of St. Louis, State of Missouri,have invented a new and Improved Ohurn-Dasher, of which the following isa full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan iew of my new and improved churn-dasher, and Figs. 2and 3 are side elevations of the same.

The invention will first be described in connection with the drawings,and then pointed out in the claims.

The main frame of the dasher is composed of the central bar a andparallel cross-pieces b l). The staff A of the dasher is mortised intothe center of the bar a, and the top of this bar is beveled in oppositedirections, as shown at a a, and its ends a are reduced in thickness andbeveled upon the under surface, as shown at a to deflect the cream. toone side when the dasher is thrust downward. The bars I) are eachbeveled at their upper surfaces, as shown at 1) 11 at the ends andcenter, and they are each beveled at the ends upon the under surface, asshown at 12 Fig. 2, and at 17 Fig. 3, so that when the dasher is forceddown through the cream the said bars will deflect it outward and to oneside.

In the bars b l) are journaled the two shafts B B, parallel with andequidistant from the central bar a. In each of these shafts is secured acentral blade d and two end blades ff. Each of the blades (1 are formedwith a round shank d, which passes through a hole in the shaft quitesnugly, so that the blade may be turned for adjusting it to any desiredangle. The under surface of the said blades d are concave, as shown at dFig. 2, and they are set at an angle, as shown in said figure, todeflect the cream against the adjacent surface of the bar I) as thedasher is forced downward. The ends of the shanks d reach over thecentral bar a, which acts as a stop to the blades cl, so that theycannot swing upward beyond a horizontal position or on a plane with thefixed bars Ct 19. The blades f are each formed with a round shank f tofit in holes near the end of the shaft B,

as shown clearly in Fig. 1, and also to permit the said blades to beturned to any desired angle for deflecting the cream. The shanks f areof a length to reach over the central bar a, so that they serve,together with the shanks (Z, to out and agitate the cream that issuesbetween the shafts B B-and the central bar a. The under surface of eachof the blades f is made concave, as shown at F, to cause them to moreeffectively agitate the cream, and the outer ends of all of the blades fand d and the ends of bars a b and shafts B B are curved, all beingstruck from the center of the dasher, so that the dasher is circular inoutline.

"When the churn-dasher is lifted up through the cream, the blades d fturn the shafts B, so that said blades droop to the position shown indotted lines in Fig. 3, and this downward deflection of the said bladesis limited by the pin on inserted in the center of the central bar a,against the ends of which the blades cl strike when turned downward, aswill be understood from Figs. 1 and 2.

WVhile I have shown my new dasher constructed for a round churn-body, itwill be understood that it may be made square to adapt it to churns ofthat form.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. As a new article of manufacture, a churndasher composed of thecentral bar CL and two parallel bars I) b at right angles to the saidcentral bar, in combination with the two shafts B B, journaled in thecross-bars Z? Z), and provided with blades (Z d, between the cross-barsb b and blades f, outside the said cross-bars, the blades being formedwith shanks to strike upon the central bar, substantially as described.

2. The central bar Cb and the two parallel bars 5 b at rightangles tothe said central bar, and the two shafts B B, j ournaled in the saidbars I) b, in combination with the blades f d, adjustably held in thesaid shafts and made concave upon their under surfaces, substantially asdescribed.
